Hi. This is a new and frightening experience for me. I have epilepsy, and get blood drawn frequently to check the levels of my meds. i was recently told that my red and white cell count was very low. i tested positive for autoimmune disease, and the ANA is 1:640. What does this mean? I have sores on my scalp that have been there since May. Some are reddish purplish and it itches all the time. This has been happening off and on since 2001. I thought it was ezcema or psoriasis. Now, i'm not too sure. Any input?
